Alas, Midwest flooding has taken my trusty N/I EGT-150.? It along with
several pieces of equipment (Haban mower, two mower decks and a nearly
completely restored rotary broom.? At 8-10 feet above flood stage the
Electric tractor was no match for waters that completely submerged
everything stored in a garage. Because of the speed of the advancing water
and a mobility issue that I have been working on I had no opportunity to
remove any of the equipment in time to keep them dry.? This week I pulled
everything out and began to survey the damage. All electrical components
have formed rusty corrosion at terminal ends and on battery posts. The
tractor is completely covered in a thin layer of mud and corn stalks!
My question for the Elec Trak experts and engineers out there:? Is it time
to say goodby to the old girl and call the scrap dealer?? Or, given enough
time could one completely disassemble it, carefully cleaning each
component upon reassembly.? Could it be saved by upgrading to an Altrax
controller?? I don't have any experience with these although I believe
that performance is better than the original design in most cases.
So. I am open to any and all suggestions from the community.
Waterlogged in Correctionville,
Chris Weinreich

If you are using flooded batteries they maybe damaged. I would say hose it
down out the key in and see what happens

I really don't have any wisdom to share beyond Chris' advice.
There's not a lot of electronics in an EGT-150. I assume any foam in
the seat is history. I expect the two main issues will be:
any old electronics like capacitors may not survive the immersion; and,
mud might end up fouling contacts in the open reed relays.
More water probably won't make the electronics any worse, and might
clean out mud and bits of debris.
After thorough washing with clean water, let dry completely before
trying anything else.
I'm assuming no major physical impact damage.
Only after that, if things seem to be mostly working, would I worry
about the batteries. I'm assuming flooded lead-acid golf car batteries.
It's a messy process, but you could drain the electrolyte, rinse the
cells with clean water, and refill with new electrolyte. Not sure how
you source the dilute sulphuric acid now. I don't think automotive
shops keep it around anymore - everything seems to ship with electrolyte
in now. Personally, I would just replace the batteries if they're the
last step to returning to reliable operation.
Sorry to hear about your unfortunate event. Sadly, as weather systems
become bigger and more erratic (compared to what we have become
accustomed to), I think many of us will be facing more maintenance
issues (beyond our electric worksteeds). I know I spend a lot more time
on tree damage cleanup than I used to do.

Thinking a bit more I'd recommend not running the mower motors but
opening them up and cleaning them out as well. The main motor might be
ok, but it should be serviced for bearings and you should check to see
it turns easily before using it. (If it doesn't mud may have gotten in)
If the battery cell tops were sealed the electrolyte might be ok. Check
it out.
Aside from that, what's the worst that could happen?

I've had to deal with some cars that were in floods here in NJ. Yes,
wash it all down and clean out any electronics. But the thing I did not
realize at first was that the flood waters contain extremely fine dirt.
This dirt gets into everything including "sealed" bearings. Most if not
all bearings will have to be replaced. The best thing to do is to get
things running as soon as possible after washing it all clean and get
oil and grease on anything that moves before rust starts.
